Résumé : |
Thermoplastic tapes are expected to achieve great things, namely to shape the next generation of thermoplastic composites. This calls for highly accurate tape stacking. At the same time, tape processing must not ‧become so complex that it becomes uneconomical. Engel contributes this technology to achieve a breakthrough by combining high-precision control software with camera technology in tape stacking. |
Note de contenu : |
- Higher structural performance
- Stacking accuracy determines quality
- The influence of gap and overlap
- Taking correction values into account for each stacking position
- High performance in real time
- Pck-and-place for hybrid stacks too
- Glas fibers and carbon fibers for different load ranges
- Fig. 1 : The laboratory production line is designed for stack dimensions up to 460 x 360 mm
- Fig. 2 : Flexural beidning test with tape blanks featuring deliberately incorporated defects : gaps and overlaps each reduce the impact strength compared with the blank produced with optimal butt alignment
- Fig. 3 : Search fields for determining edge runs : measurements are taken at 25 positions to join the points together by means of a line of best fit
- Fig. 4 : The corner position results from the detemrined edge runs. This method is much more accurate than direct optical measurement because tapes do not always have sharp corners
- Fig. 5 : The ready-cut tape are separated at the stacking magazines and held in position on pick tables for collection by the robots |
